The Center of Gravity (CG) maximum is 63 (1600 mm) above the ground. Figure NOTE: The Final Manufacturer must ensure that the combined vertical center of gravity of the chassis, body, and available payload at full GVW does not exceed the maximum vertical center of gravity outlined in the Isuzu Incomplete Vehicle Document and the Isuzu Body Builders Guide. The maximum dimensions for a body installed on the N Series chassis are 102 inches wide (outside*) by 91 inches high (inside). Any larger body applications must be approved by Isuzu Commercial Trucks of America (ICTA) Application Engineering.

EW Maximum Rear Width: C Centerline of axle to top of frame rail at curb position. Overall width of the vehicle measured at the outermost surface of the rear tires. D Centerline of axle to top of frame rail at design load. HH Rear Tire Clearance: Minimum clearance between the rear axle and the ground-line. E Rear Tire Clearance: Minimum clearance required for tires and chain measured from the top of the frame at the vertical centerline of the rear axle, when rear wheels on one side ride over a high spot. Dual Tire Spacing: HW Distance between the centerlines of the minimum distance required for tire bounce as measured from the centerline of the rear axle and the top of the rear tire when one wheel rides over a high spot. CH DH Rear Frame Height: Vertical distance between the normal top of frame rail and the ground-line through the centerline of the rear axle at curb position. Rear Frame Height: Vertical distance between the normal top of frame rail and the ground-line through the centerline of the rear axle at design load.
